Monitoring relay for monitoring the phase sequence and asymmetry of 3-phase voltages at 208 ... 480 V
AC/120 ... 277 V AC, configurable asymmetry, 1 PDT, with push-in connection
Product description
Safety and system availability requirements are constantly on the increase – across all industries. Processes are becoming more and more complex, not
only in machine building and the chemical industry but also in building technology. The demands placed on energy technology are also constantly on the
rise.
It is only by continuously monitoring key network and system parameters that error-free and therefore cost-effective operation can be achieved.
Electronic monitoring relays from the EMD series are available for a wide range of monitoring tasks so that the consequences of errors can be avoided
or kept within limits.
The operating states are signaled via color LEDs and any errors that occur can be sent to a controller via a floating contact or can shut down a section
of the system. All device versions are equipped with response delays so that measured values outside the set monitoring range can be briefly tolerated. 
